Missing SeedFertilizer_desc in l10_nl

Hello Comm. I have a problem with de HoT_Seedfertilizer_placeable_Final and specially with the liquidFertilizer. I'm not able to load the machine with the required stuff. Water goes well, bud the liquid manure won't go and in the buy menu there is an error under the equipment : Missing SeedFertilizer_desc in l10_nl.xml. Are there more people having this error and more important, what is the solution? Because I have those machines and I will have them to get working
